x86 consolidation in svn trunk

If you're not using the svn trunk, feel free to ignore this.

For the last several months, we've maintained the Darwin x86-64 version of
CCL in the subversion trunk at

http://svn.clozure.com/publicsvn/openmcl/trunk/darwinx8664/ccl

For the last few weeks, a 32-bit x86 Darwin version has also been 
available at

http://svn.clozure.com/publicsvn/openmcl/trunk/darwinx8632/ccl

A new directory (containing binaries for both 32- and 64-bit x86 Darwin,
interfaces and common sources is available at:

http://svn.clozure.com/publicsvn/openmcl/trunk/darwinx86/ccl

The old (word-size specific) directories will likely be deprecated
and removed soon.  If you've been using a working copy based on
one of these older directories, please switch to the new consolidated
directory ASAP.

This is fairly easy to do in svn:

1) cd to the ccl directory and ensure that it's up to date with respect
to the old URL.  (The latter part may not be strictly necessary, but can't
hurt.)

shell> cd ccl
shell> svn update
